Abstract

AN ELECTRONIC EQUIPMENT HAVING THE FUNCTION OF DISPLAYING THE BATTERY RESIDUAL QUANTITY FOR DISPLAYING THE USABLE RESIDUAL TIME OF A BATTERY PACK (1) USED AS A POWER SOURCE OF THE ELECTRONIC EQUIPMENT. THE EQUIPMENT IS DESIGNED TO COPE WITH DIFFERENT TYPES OR FUTURE VERSION OF THE BATTERY CELL (20). THE RESIDUAL USABLE TIME OF THE BATTERY CAN BE KNOWN WITH IMPROVED DISPLAY ACCURACY. THE VIDEO CAMERA (60) CARRIES A BATTERY PACK (1) OUTPUTTING AT LEAST THE INFORMATION ON THE RESIDUAL BATTERY CAPACITY, CHARGING/ DISCHARGING CURRENT DETECTION INFORMATION AND THE BATTERY CELL VOLTAGE DETECTION INFORMATION. THE VIDEO CAMERA (60) INCLUDES A MICRO-COMPUTER (63) HAVING A COMMUNICATION CIRCUIT (65) FOR RECEIVING THE ABOVE INFORMATION FROM THE BATTERY PACK (1), A CALCULATION CIRCUIT (66) FOR CALCULATING THE CURRENT RESIDUAL BATTERY CAPACITY BASED ON THE INFORMATION FROM THE BATTERY PACK (1) RECEIVED BY THE COMMUNICATION CIRCUIT (65), AND A DISPLAY CONTROL CIRCUIT (67), AND A DISPLAY DEVICE (64) FED WITH A DISPLAY SIGNAL CORRESPONDING TO THE RESULTS OF CALCULATIONS BY THE CALCULATION CIRCUIT (66) OF THE MICRO-COMPUTER (63) FOR DISPLAYING THE RESIDUAL BATTERY CAPACITY BASED ON THE DISPLAY SIGNAL.FIGURE 1
